10:00 PM – The No-Knead Dough: In a large bowl, completely dissolve the 3.85g of instant yeast into the mixture of 108g of water and 109g of milk. Add the 32g of sugar, 8g of salt, and all 350g of high-protein bread flour.

The Overnight Fridge Rest: Mix the ingredients thoroughly by hand or on the lowest speed of your mixing machine just until a cohesive mass forms. Do not over-knead or try to develop a strong gluten network at this stage. The dough can remain slightly lumpy; the gluten matrix will naturally organize and develop all on its own overnight. Wrap the dough tightly in plastic wrap and place it into the refrigerator until the next morning (roughly 10 hours).

8:00 AM – The Pliable Butter Block: Cut your 205g of cold high-fat pastry butter into sheets and place them in the center of a large piece of parchment paper. Fold the paper edges inward to form a clean, closed 12x14 cm (approx. 5x5.5 inch) square envelope. Flip the package over and roll firmly with your rolling pin to push the butter flat into the corners of the paper. Place the butter envelope into the fridge for 15 minutes to chill down. (The Temperature Sweet Spot: The butter must be completely pliable—bends easily without cracking—yet remain cold. If it's rock-hard, it will shatter inside your dough layers; if it's too soft, it will melt into the flour).

Enclosing the Butter: Remove your cold dough from the fridge. Dust your counter lightly with flour and roll the dough out into a clean square large enough to comfortably enclose the butter (about 25x25 cm / 10x10 inches). Place the cold butter block diagonally in the center of the dough, pull the four exposed corners of the dough into the center like an envelope, and pinch the seams tightly together to trap the butter inside.

1st & 2nd Letter Folds: Gently tap the dough with your rolling pin to spread the butter evenly, then roll it out lengthwise into a long rectangle. Trim the folded uneven skin at the very top and bottom edges and place those scraps on top of the dough to relieve rolling tension. Fold the bottom 1/3 of the dough sheet up over the center, then fold the top 1/3 down over it like a letter. Rotate the dough package 90 degrees, roll out long a second time, trim the ends, and fold it into a letter once more. Wrap tightly and chill in the fridge for 1 full hour.

3rd Final Fold: Remove the chilled dough from the fridge. Roll it out lengthwise a third time, trim the uneven ends, and execute your third and final standard letter fold. Wrap the dough and place it back into the refrigerator for 1 final hour to completely relax the gluten.

10:30 AM – Rolling the Sheet: Remove your laminated dough from the fridge. Carefully roll it out into a long, flat rectangle until it reaches a uniform thickness of 4 to 5 mm (about 0.15 inches), ensuring the short side of your rectangle measures roughly 23 to 26 cm (9 to 10 inches) wide.

Triangle Cutting: Use a long, sharp knife or pizza wheel to trim away all uneven outer edges cleanly to expose the inner lamination. Cut out elongated triangles from the sheet, ensuring the base of each triangle measures exactly 8 cm (approx. 3.1 inches) wide.

Shaping the Horns: Grab the base of a triangle, stretch it slightly in width, and gently elongate the tip with your fingers. Roll the dough up smoothly from the wide base all the way to the narrow tip, ensuring the point rests squarely on the bottom of the roll to prevent unravelling. Place the shaped croissants onto a baking sheet lined with parchment paper, leaving ample space between them.

The Voluminous Jiggly Proof: Cover the croissants loosely. Let them proof undisturbed for 4 to 5 hours at a warm room temperature of 74–78°F (24–26°C) until they completely double in size, reveal distinct side layers, and wobble like jelly when you gently shake the pan. (The Baker's Timeline Alternative: If you prefer freshly baked morning pastries, you can place the covered sheet into the fridge until late evening, then pull them out to proof overnight on your kitchen counter at a cool 68–72°F / 20–22°C to bake first thing in the morning).

Baking: Preheat your home oven to 375°F (190°C). Whisk 1 whole egg with 2 tablespoons of water until completely smooth. Use a pastry brush to sweep the egg wash gently across the top ridges of each proofed croissant, making sure the egg doesn't pool in the laminated layers.

Cooling: Slide the baking sheet onto the middle rack of the preheated oven. Bake at 375°F (190°C) for 25 to 30 minutes until the pastries turn a deep, uniform golden brown. Transfer them to a wire rack and let cool for 15 minutes before cracking into those buttery, shatteringly crisp layers!
